What you said doesn't make any sense, but that's not important. What
I meant is that surely there's some policy you can work on instead of
this semantic hair-splitting over whether it's ok for a package to
have an executable as a maintainer "script".

No, Raul, that's the whole point. When you're upgrading libc5->libc6,
/bin/sh really does stop working until this postinst runs.
It's a C program because that makes it more robust. There is a very
small set of programs which will render your system unusable if they
stop working. The C library and ld.so are already on that list so
there's no point in making this postinst statically linked. Perl is
not on that list so there is a point in not writing it in perl.
